Abstract
Aspects of the present disclosure relate to antistatic articles, including systems, and methods of use thereof. The article can include a fabric layer having a first fabric side and a second fabric side, and a polymeric antistatic layer disposed in a direction towards the second fabric side. The polymeric antistatic layer comprises an antistatic polymer.
Claims
exact text as granted — not AI-modified1 . An article comprising:
a fabric layer having a first fabric side and a second fabric side; and a polymeric antistatic layer disposed in a direction towards the second fabric side, wherein the polymeric antistatic layer comprises an antistatic polymer.
2 . The article of claim 1 , wherein the fabric layer comprises a nonwoven fabric, woven fabric, knitted fabric, or combinations thereof.
3 . The article of claim 1 , wherein the antistatic polymer is a primer for an adhesive layer.
4 . The article of claim 1 , further comprising:
a polymer film layer having a first film side and a second film side; wherein the polymer film layer is sandwiched between the fabric layer and the polymeric antistatic layer.
5 . The article of claim 4 , wherein the first film side is disposed on the second fabric side, and the polymeric antistatic layer is disposed on the second film side.
6 . The article of claim 5 , wherein the polymeric antistatic layer has a first antistatic side and a second antistatic side, wherein the first antistatic side contacts the second film side.
7 . The article of claim 1 , further comprising an adhesive layer having a first adhesive side and a second adhesive side, wherein the first adhesive side is disposed on the polymeric antistatic layer.
8 . The article of claim 7 , wherein the first adhesive side is disposed on the second antistatic side.
9 . The article of claim 8 , wherein a charge decay of the article is less than 0.02 seconds between 16% and 30% (inclusive) relative humidity.
10 . The article of claim 1 , wherein the polymeric antistatic layer comprises an acrylate copolymer, comprising a crosslinking agent in an amount of at least 2 weight percent of the total weight of the polymeric antistatic layer.
11 . The article of claim 10 , wherein the crosslinking agent comprises diacetone acrylamide.
12 . The article of claim 10 , wherein the crosslinking agent is a difunctional crosslinking agent, the difunctional crosslinking agent is adipic dihydrazide or adipic acid dihydrazide.
13 . The article of claim 1 , wherein the article does not include metal or metal salts thereof or non-polymeric quaternary ammonium salts such as ammonium chloride.
14 . The article of claim 1 , wherein only the polymeric antistatic layer has antistatic properties.
15 . The article of claim 14 , wherein the fabric layer or adhesive layer is not treated with antistatic materials.
16 . The article of claim 1 , wherein the polymeric antistatic layer comprises a primer layer and a conductive polymer layer.
17 . The article of claim 16 , wherein the conductive polymer layer comprises PEDOT-PSS.
18 .- 19 . (canceled)
20 . A method comprising:
applying the article of claim 1 to a substrate at room temperature; allowing the article to protect the substrate from liquids to form a soiled article; removing the soiled article from the substrate by peeling the soiled article at room temperature.
21 . The method of claim 20 , wherein a static charge produced at an interface between the soiled article and the substrate is dissipated through the polymeric antistatic layer.
22 . The method of claim 21 , wherein the adhesive layer stays attached to a polymer film layer when the soiled article is removed.
